this is the most current revision of my original design mainbearing mold for babbitted bearings in the model T engine ...this design mold will pour all bearings in both the block and caps ( 1 bearing at a time )...bearing is poured at 1 1/8" diameter with .030 excess material per side on thrust surfaces ...this allows for machining to standard or any reasonable undersize diameter and correct positioning and fit of thrust surfaces ...price of $100 + $10 postage in lower 48 states includes mold and written instructions and my telephone or email support ...this is not a copy of any existing design , past or present ...I have been building these products since 1979 ...gene French 230 Rochester dr.
